The monotypic genus Mymarilla Westwood is known only from St. Helena, a remote island in the South Atlantic Ocean. The peculiar species M. wollastoni Westwood (Mymaridae) is redescribed and illustrated from non-type material. Mymarilla is compared with Cremnomymar Ogloblinspp. from the Juan Fernández Islands in the South Pacific Ocean. Stephanodes Enock is shown to be the most likely sister genus to Mymarilla. Nesopolynema Ogloblin, syn. n., Oncomymar Ogloblin, syn. n., Scolopsopteron Ogloblin, syn. n., are placed in synonymy under Cremnomymar and their species transferred as Cremnomymar caudatum (Ogloblin 1952), comb. n., C. dipteron (Ogloblin 1957), comb. n., and C. kuscheli (Ogloblin 1952), comb. n. Wing shape and wing reductions in Mymaridae are discussed in relation to biogeography, particularly with respect island faunas and to four genera, Cremnomymar, Mymarilla, Parapolynema Fidalgo, and Richteria Girault, some or all of whose species have more or less convex fore wings.

单型属拟柄翅小蜂属（Mymarilla）仅见于南大西洋的偏远岛屿圣赫勒拿岛。本文依据非模式标本对该属的特有物种沃拉斯顿拟柄翅小蜂（M. wollastoni Westwood）（柄翅小蜂科）进行了重新描述和绘图。将拟柄翅小蜂属与南太平洋胡安·费尔南德斯群岛的隐柄翅小蜂属（Cremnomymar）进行了比较。结果表明，斯氏柄翅小蜂属（Stephanodes）是拟柄翅小蜂属最有可能的姐妹属。隐柄翅小蜂属新异名包括奥氏寡节柄翅小蜂属（Nesopolynema Ogloblin）、瘤柄翅小蜂属（Oncomymar Ogloblin）、鞘柄翅小蜂属（Scolopsopteron Ogloblin），其物种分别作为尾状隐柄翅小蜂（Cremnomymar caudatum）（奥格洛布林，1952）、双翅隐柄翅小蜂（C. dipteron）（奥格洛布林，1957）和库氏隐柄翅小蜂（C. kuscheli）（奥格洛布林，1952）进行转属组合。本文结合生物地理学，特别是岛屿动物区系，以及隐柄翅小蜂属、拟柄翅小蜂属、副寡节柄翅小蜂属（Parapolynema Fidalgo）和里氏柄翅小蜂属（Richteria Girault）这四个属，讨论了柄翅小蜂科的翅形和翅退化情况，其中部分或所有物种的前翅或多或少呈凸形。
